What are the vertical wind turbine generators?
Vertical axis wind turbine generator is characterized by vertical axis and the ground, easy to install and easy to maintain, do not need the windward device, simplifying the structure. The vertical axis wind turbine can accept the wind in any direction of the 360 degree azimuth, and the spindle always rotates towards the design direction.
1. high security. The use of vertical blade and triangular double fulcrum design, and the main force concentrated in the vertical hub, so leaves off, broken and leaf fly out and other issues have been a better solution;
Noise The use of horizontal rotation and blade application aircraft wing design, making the noise reduced to the extent of the natural environment can not be measured;
3. Stronger wind resistance. Horizontal rotation and triangular double fulcrum design principle, making it subject to wind pressure is small, can withstand 45 meters per second super typhoon;
4. Rotation radius is small. Because of its design structure and operating principle of different, than other forms of wind power has a smaller radius of rotation, saving space, while improving efficiency;
5. Low wind power generation high. Start the wind speed is lower than other forms of wind turbines, the power generation rate of increase is relatively flat, so in the 5 to 8 meters wind speed range, its power generation than other types of wind turbines 10% to 30%
6. Use a wide range of wind speed. Using a special control principle, so that it is suitable for running the wind speed range expanded to 2.5 ~ 25m / s, in the maximum use of wind resources at the same time to obtain a larger total power generation, improve the use of wind power equipment economy;
7. Brake device. Configurable mechanical manual and electronic automatic brakes in two areas without typhoon and super gusts, just set the manual brake can be;
8. Operation and maintenance. Direct drive type permanent magnet generator, no gear box and steering mechanism, regular (usually every six months) on the operation of the connection can be checked.
Vertical shaft wind turbine blade tip speed is smaller than the horizontal axis, starting noise is small, suitable for urban public facilities, street lamps, house and other noise can not be too high places, roads, transportation, residential, office monitoring and other places. Vertical axis wind turbines have a wider range of applications and prospects.
